g .The invention relates to sheet metal barrel or drums and provides certain improvementsin the rolling provisions therefor.

Itis conventional practice to provide metal containers of the type indicated withrolling hoops sometimes manifested as outwardly directed circumferential corrugations of the shell and sometimes as rails or bars off-beam or other section on or otherwise secured to the shell. Metal hoops are objectionable because they operate to, cut and otherwise damage polished and other expensive floors and because they operate to mar the surfaces'of adjacent barrels and drums. It has heretofore been proposed to I replace the'metal hoops with rubber and other elastic hoops but they have not been satisfactory for one reason or another and becauseno satisfactorynieahs were suggested for anchoring them.

According tomy invention the shell of the container is provided with relatively closely spaced circumferentialbeads for the purpose and with the resultof anchoring a generally dome-shaped rubber structure having grooves to accommodate the beads and flanges or shoulders extending beyon d the beads and secured'by contracting bands,

the dome-shaped structure being of suflicient depth or thickness to constitute -a rolling hoop.

The invention in its preferred form is illustrated in the accompanying drawing, forming a part 80 hereof, wherein-.

Figure 1 is a sectional view of a sheet metal barrel or having a rubber hoop constructed, anchored, and securedin accordance with my invention. as Fig. 2 is a view principally in side elevation showing the meansfor contracting the bands.

In the drawing. .5 represents the shell of aconventional sheet metal barrel or drum, headedns usual 8 denotes circumferential beads formed as outwardly directed corrugations of the shell-and relatively closely 'by seating: 1.

' .The paired beads serve to anchor a rubber hoop 8 which in section is of general dome-shape. The hoop is by preference of solid construction with shoulders or flanges 9 having overlying grooves or channels to accommodate contractible bands 6 Ill. Inwardly of. the shoulders and relatively spaced apart are grooves ll contoured to fit the beads. The hoop may be applied 'as an endless band or it may be of the split type with the ends v joined as by cementing, vulcanization or in any 10 other conventional way. when the parts are assembled and arranged in the manner stated, the bands III are joined and contracted through the medium of .tumbuckles l2.\

It will'be manifest that by the construction and arrangement stated and by virtue of the relative angular arrangement of the anchoring beads and the securing bands, the hoop will beproperly anchored and comparatively. free of tendency "toward-lateral deformation. I

Having described as new is:- I v 1. A metal barrel ordrum whereof the cylindrical wall is provided with a channular seat having a flat bottom and sloping'side walls deflned B5 by a pair of circumferential arcuatebeads, combined with a solid rubber hoop whereof the main body portion has a rounded tread and a bottom rib to flt the channular seat, said rib being defined by a pair of grooves which match the beads and snugly fit the same, said main body portion having flexible flanges extending beyond the beads, and means overlying the flanges to contract them and thereby hold the hoop rigidly stationary with relation to its seat. 2. The invention set forth in claim 1 in which said overlying means comprises a wire with threaded ends and a small .tumbuckle engaging said ends, the wire and turnbucklebeing well within the confines of the hoop. 40
